Shibarium PoS architecture: Ethereum mainnet, Heimdall, and Bor layers

Shibarium is a multi-layered Proof-of-Stake (PoS) blockchain network designed for scalability, security, and efficiency. It leverages the security of Ethereum while providing fast, low-cost transactions through its own validator and consensus layers. The native staking token for Shibarium is BONE.
Shibarium PoS architecture is inspired by Polygon PoS, but uses BONE as the staking and governance token.

​
Architecture Layers

  • Staking Contracts: Manage validator staking and delegation using BONE tokens.
  • Checkpoint Contracts: Record periodic snapshots (checkpoints) of the Shibarium chain to Ethereum, ensuring data integrity and security.
  • Rewards Contracts: Distribute staking rewards to validators and delegators.
  • Proof of Stake: Heimdall is the validator layer responsible for managing validator sets, producing checkpoints, and relaying them to Ethereum. Validators stake BONE to participate in consensus and secure the network.
  • EVM Compatibility: Bor is the block producer layer, fully compatible with the Ethereum Virtual Machine (EVM), enabling seamless deployment of smart contracts and dApps.
  • Fast Consensus: Bor achieves rapid block production and transaction finality, supporting high throughput and low fees.

​
How It Works

1

Stake BONE on Ethereum

Validators and delegators lock BONE tokens in staking contracts on Ethereum mainnet to participate in Shibarium’s PoS consensus.
2

Heimdall Validates and Checkpoints

Heimdall validators collect transactions, produce checkpoints, and submit them to Ethereum for security and finality.
3

Bor Produces Blocks

Bor nodes create blocks, execute EVM transactions, and maintain the Shibarium chain with fast consensus.
4

Earn Rewards

Validators and delegators receive BONE rewards for securing the network and maintaining uptime.
Shibarium’s architecture ensures security by anchoring to Ethereum, while delivering speed and low fees through its own validator and block producer layers.
